Airport infrastructure evolves alongside legacy systems and processes that limit the ability to fully realise the efficiency potential of costly renovations. Airports will continue to take advantage of current and future technologies. Nevertheless, for such systems to work as efficiently as possible, the passenger should play an active role. This p...
Airport operations are undergoing significant change, having to meet pandemic requirements in addition to intrinsic security requirements. Although air traffic has declined massively, airports are still the critical hubs of the air transport network. The new restrictions due to the COVID-19 pandemic pose new challenges for airport operators in rede...
COVID-19 arrived in the world suddenly and unexpectedly. It caused major disruptions at economical, operational, and other levels. In the case of flight traffic, the operations were reduced to 10% of their original levels. The question after COVID-19 is how to restart the operations and how to keep the balance between safety and capacity. In this p...
Passenger flow management is an important issue at many airports around the world.

Mexico City airport is the main gateway to the country since years ago. However, its growth has been hampered by the saturation of the airport which in most slots of the day it is impossible to accommodate more traffic. The latter can be only achieved by performing three activities: infrastructure expansion, optimization of the current resources or...
The constant growth of air traffic, especially in Europe, is putting pressure on airports, which, in turn, are suffering congestion problems. The airspace surrounding airport, terminal manoeuvring area (TMA), is particularly congested, since it accommodates all the converging traffic to and from airports. Besides airspace, airport ground capacity i...
L'augmentation constante du trafic aérien, spécialement en Europe, exerce une pression sur les aéroports, qui en conséquence sont souvent congestionnés. La zone aérienne entourant les aéroports, l'aire de manœuvre terminale (TMA), est particulièrement encombrée, puisqu'elle accueille tout le trafic aéroportuaire. Outre la zone aérienne, le partie s...
